种族歧视的经历可能会导致非裔美国人的压力诱发血压(BP)升高。据报道，觉察到的种族主义与清醒时的动态血压(ABP)有关。这项研究考察了40名非裔美国大学生对种族主义和总部基地的感知，他们完成了总部基地评估，并根据评估结果计算了白天和夜间的平均值。使用感觉种族主义量表衡量感受到的种族主义和种族歧视经历的频率。控制性别和体重指数，在学术环境中感受到的种族主义与清醒时间和夜间睡眠时较高的舒张压(DBP)相关。收缩压(SBP)与感受到的种族主义无关，在公共领域感受到的种族主义和在白人的声明中感受到的种族主义与ABP无关，学术环境中感受到的种族主义可以预测大学生中的动态DBP。先前的实验室研究发现，感觉到的种族主义对DBP的影响比SBP更大，BP的血流动力学调节可能解释了这种现象。未来的实验室和动态研究应该评估血管阻力和心输出量对与感知到的种族主义相关的血压升高的贡献。
Experiences with racial discrimination may contribute to stress-induced blood pressure (BP) elevations among African Americans. It was reported that perceived racism was associated with ambulatory BP (ABP) during waking hours. This study examined perceived racism and ABP among 40 African American college students, who completed an ABP assessment from which daytime and nighttime averages were computed. Perceived frequency of experiences with racism and racial discrimination was measured using the Perceived Racism Scale. Controlling for gender and body mass index, perceived racism in academic settings was associated with higher diastolic BP (DBP) during waking hours and nighttime sleep. Systolic BP (SBP) was unrelated to perceived racism, and perceived racism in the public realm and in statements from Whites was unrelated to ABP Perceived racism in academic settings predicted ambulatory DBP among college students. Previous laboratory research has found stronger effects of perceived racism for DBP than SBP The hemodynamic regulation of BP may explain this phenomenon. Future laboratory and ambulatory studies should assess the contributions of vascular resistance and cardiac output to BP elevations associated with perceived racism.
